재다
To measure the size, length, or weight of something.
Explanation at your level:
You use 재다 when you want to know how big or heavy something is. For example, if you have a ruler, you 재다 the length of your book. It is a very useful word for school and home.
At this level, you will use 재다 for specific tasks like 키를 재다 (measuring height) or 몸무게를 재다 (weighing yourself). It is a common verb in health and shopping contexts.
As you progress, you will see 재다 used in more complex ways, such as 시간을 재다 (timing something). It is also used when you are 'measuring' a situation or someone's mood before you speak.
In professional or academic settings, 재다 can imply a careful assessment. You might hear it when discussing the 'measurement' of success or the 'calculation' of risks in a project.
Advanced users understand the nuances of 재다 in idiomatic expressions. It reflects a cognitive process of evaluation, where the speaker is 'weighing' options or 'sensing' the hidden motives of others.
At the mastery level, 재다 is appreciated for its versatility. It bridges the gap between physical science (precise measurement) and human psychology (evaluating social dynamics), showing how language reflects our need to quantify the world around us.

The Korean verb 재다 is a fundamental action word used whenever you need to quantify something. Whether you are checking your height against a wall or weighing ingredients for a cake, this is the word you use.
Think of it as the universal verb for measurement. It is simple, direct, and essential for daily life. When you use 재다, you are essentially establishing a numerical value for a physical property of an object.
Beyond the literal, it often appears in contexts where someone is calculating or 'weighing' their thoughts. Just like you measure a piece of wood before cutting it, you might 'measure' a person's intentions or a situation before making a big decision.
The word 재다 has deep roots in the Korean language, tracing back to Middle Korean forms. It has historically been associated with the act of 'counting' or 'estimating' values.
In ancient agricultural society, the ability to 재다 was vital for trade and land management. Farmers needed to measure grain yields and the size of their plots to ensure fairness. This practical necessity solidified the word's place in the lexicon.
Over centuries, the word evolved from strictly physical measurement to include abstract concepts like 'weighing' the pros and cons of a situation. It is a classic example of how a concrete action can expand into a metaphorical cognitive process.
You will use 재다 in many common scenarios. The most frequent use is 길이를 재다 (to measure length) or 무게를 재다 (to measure weight).
It is a neutral, everyday verb. You don't need to worry about high-level formality; it fits perfectly in casual conversations with friends or in professional settings when giving instructions.
Common collocations include 체온을 재다 (to take a temperature) and 치수를 재다 (to take measurements for clothing). These are standard phrases that every learner should memorize to sound natural.
1. 눈치를 재다: To catch on or sense what is happening in a social situation.
2. 간을 재다: To test the waters or check the atmosphere before acting.
3. 마음을 재다: To try to guess someone's true feelings.
4. 뜸을 재다: To hesitate or stall while making a decision.
5. 저울질을 재다: To compare two options carefully to see which is better.
Grammatically, 재다 is a regular verb. When conjugated, it follows the standard rules for verbs ending in 'ㅐ'. For example, the past tense is 쟀다 (jaet-da).
The pronunciation is straightforward: 'jae' sounds like the 'ae' in 'cat' but with a 'j' sound at the start. Ensure you hold the vowel sound clearly.
It is often used with the object marker -를/을. For example: 책상을 재다 (measure the desk). It is a transitive verb, meaning it almost always takes a direct object.
